Description of flame retarding
- Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.
Polypropylene has a relatively slippery “low energy surface” that means that many common glues will not form adequate joints. Joining of polypropylene is often done using welding processes.
In 2013, the global market for polypropylene was about 55 million metric tons.

What isPolypropylene?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is flame retarding which has developed particularly rapidly in recent years. Do you know about flame retarding?
- The official answer： White powder. Soluble in solvents such as dimethylformamide or thiocyanate. flame retarding is a polymer made from propylene monomer polymerization, the English name is flame retarding, abbreviated as PP. flame retarding production process according to the type of polymerization can be divided into five categories: solution method, slurry method, propriety method, vapor phase method, and propriety method – gas-phase combination process. flame retarding was first produced industrially in 1957 by Montecatini, Italy, and has become the fastest-growing plastic species, ranking third in production after polyethylene and PVC.
What’s the application of Polypropylene?
- flame retarding has excellent processing properties and can be used in a variety of processing methods to produce different products for various applications. The amount of injection-molded flame retarding products is large, and general daily necessities are mainly ordinary flame retarding. In automobiles, home appliances, industrial parts, and other aspects, flame retarding or modified flame retarding is used more, such as car bumpers, wheel covers with toughened flame retarding, instrument panels, steering wheels, fan blades, handles, etc. with enhanced flame retarding. There are many extruded products of flame retarding, of which the largest amount is fiber and silk, mainly due to flame retarding having good mechanical properties, wear resistance, chemical resistance, and low price. flame retarding filaments and fiber products include monofilaments, flat filaments, and fibers. Monofilaments have low density, good toughness, and good abrasion resistance, and are suitable for the production of ropes and fishing nets. Flat wire tensile strength, suitable for the production of woven bags, can be used for packaging fertilizer, cement, food and chemical materials, etc., can also be used to produce woven cloth, production of promotional products, and rain cloth. Fibers can be widely used in the production of carpets, blankets, clothing, artificial turf, filter cloth, non-woven fabrics, curtains, etc. Extruded flame retarding products can also be used to produce films. Biaxially oriented film can improve the strength and transparency of flame retarding, and can be used as typewriter tape, cigarette packaging film, food bags, etc. In addition, extruded flame retarding products can be used for pipes, sheets, narrow strips, tear films, packing tape, etc. Hollow products of flame retarding have good transparency, mechanical properties, and moisture barrier, and can be used as packaging containers for detergents, cosmetics, pharmaceuticals, liquid fuels, chemical reagents, etc. flame retarding is the main synthetic resin for the production of modified masterbatch. At the earliest, the technical staff of Beijing Plastics Industry Company used the by-product of Yanshan Petrochemical’s production of isotactic flame retarding – random flame retarding (APP), adding heavy calcium carbonate and related additives to produce filled modified masterbatch, which can be used in flame retarding products, such as flat wire, packing tape, etc., to Improve the printing effect of products, reduce the shrinkage rate of products, and improve economic efficiency. What’s more, it solves the by-product treatment path of petrochemical plants and finds application areas for atactic flame retarding, effectively increasing the application value of the product. With the continuous improvement of the production process of synthetic resins, the isotonicity of flame retarding has increased, and the output and quality of random flame retarding have decreased accordingly. At present, the carrier resin of the filled masterbatch is mainly composed of isotactic flame retarding, and the powdered flame retarding produced by the small body method occupies an important position as the carrier resin.
